ffbf9cf3f9 clk: renesas: cpg-mssr: Use enum clk_reg_layout instead of a boolean flag
Geert suggested defining multiple register layout variants using an enum
[1] to support further devices like R-Car V3U.  So, use enum
clk_reg_layout instead of a boolean .stbyctrl flag.  No behavioral
change.

9c561be8d8 clk: renesas: r7s9210: Always use readl()
On arm32, there is no reason to use the (soon deprecated) clk_readl().
Hence use the generic readl() instead.

This is only used in this file, so mark it static to silence a sparse
warning.

b9553c13b1 clk: renesas: r7s9210: Convert some clocks to early
The OSTM timer driver for RZ/A2 uses TIMER_OF_DECLARE which requires the
ostm module clocks to be registers early in boot.

fde35c9c7d clk: renesas: cpg-mssr: Add R7S9210 support
Add support for the R7S9210 (RZ/A2) Clock Pulse Generator and Module
Standby.

The Module Standby HW in the RZ/A series is very close to R-Car HW, except
for how the registers are laid out.
The MSTP registers are only 8-bits wide, there are no status registers
(MSTPSR), and the register offsets are a little different. Since the RZ/A
hardware manuals refer to these registers as the Standby Control Registers,
we'll use that name to distinguish the RZ/A type from the R-Car type.
